百度地图申请KEY，定位和获取周边热点

百度地图申请key

一 打包：

1.先用android studio 生成 key.store

2.点击Build--Generate Signed APK...

3.create new...

4.输入E:\key.store

5.输入密码

6.key下的Alias中输入key

7.输入key的密码

8.Certificate中输入。。随便输入，点OK完成

9.返回来，输入密码。key alias中输入刚刚的key

10.下一步

二 获取SHA1 的值

1.打开Android Studio的Tools->Open Terminal...

2.定位到key.store 所在的位置

3.输入命令：keytool -v -list -keystore key.store

4.输入密码

/**百度地图定位配置*/

1.到官方下载这两个包

armeabi/liblocSDK5.so

locSDK_5.0.jar

导入lib里面

2.AndroidManifest.xml配置文件的<application> 中配置 <service>和 <meta-data>

<service

android:name="com.baidu.location.f"

android:enabled="true"

android:process=":remote" >

<intent-filter>

<action android:name="com.baidu.location.service_v2.2" >

</action>

</intent-filter>

</service>

<!--配置key-->

<meta-data

android:name="com.baidu.lbsapi.API_KEY"

android:value="VRMNc7QoiSM5ar5at5g3lRQD" />

3.在build.gradle中的android{}中配置

//定位要的配置以下代码

sourceSets {

main {

res.srcDirs = [‘src/main/res‘, ‘src/main/res/values-zhccccc‘]

assets.srcDirs = [‘src/main/assets‘, ‘src/main/assets/2‘]

jni.srcDirs = [‘src/main/jni‘, ‘src/main/jni/‘]

jniLibs.srcDirs = [‘libs‘]

}

}

4.代码中添加定位控件和监听

a.定义变量

/**定位控件*/

LocationClient mLocClient;

/**定位监听*/

public MyLocationListenner myListener;

b.初始化

 public void initdingwei(){
        // 定位初始化
        myListener = new MyLocationListenner();
        mLocClient = new LocationClient(this);
        mLocClient.registerLocationListener(myListener);
        LocationClientOption option = new LocationClientOption();
        option.setOpenGps(true);// 打开gps
        option.setCoorType("bd09ll"); // 设置坐标类型
        option.setScanSpan(2000); // 设置扫描间隔，单位是毫秒
        option.setIsNeedAddress(true);// 设置是否需要地址信息，默认为无地址
        mLocClient.setLocOption(option);
        mLocClient.start();
    }

c.设置监听器

 /**
     * 定位SDK监听函数
     */
    public class MyLocationListenner implements BDLocationListener {
        @Override
        public void onReceiveLocation(BDLocation location) {
            if (location == null) return;
            Log.i(TAG, "SDK监听函数11-->" + location.getLatitude() + " " + location.getLongitude() + " " + location.getCity());

	}

        public void onReceivePoi(BDLocation poiLocation) {

        }
    }

d.在需要定位的时候调用initdingwei()方法

/**百度地图接口之获取周边热点*/

 /**
     * 查询周边
     * http://api.map.baidu.com/place/v2/search
     * ak=您的密钥&
     * output=json&
     * query=%E9%93%B6%E8%A1%8C&
     * page_size=10&
     * page_num=0&
     * scope=1&
     * location=39.915,116.404&
     * radius=2000
     */
    public void getdata() {
        HttpUtils http = new HttpUtils();
        RequestParams params = new RequestParams();
        try {
            params.addBodyParameter("query", URLEncoder.encode("银行", "UTF-8"));

            params.addBodyParameter("output", "json");
            params.addBodyParameter("ak", "VRMNc7QoiSM5ar5at5g3lRQD");
            params.addBodyParameter("scope", "1");
            params.addBodyParameter("page_size", "10");

            http.send(HttpRequest.HttpMethod.POST,

                            try {
